For an embodiment, a memory array has a plurality fins protruding from a substrate. A tunnel dielectric layer overlies the fins. A plurality floating gates overlie the tunnel dielectric layer, and the floating gates correspond one-to-one with the fins protruding from the substrate. An intergate dielectric layer overlies the floating gates. A control gate layer overlies the intergate dielectric layer. Each fin includes an upper surface rounded by isotropic etching.
